How to Update Sony Drivers by Myself?

There are a variety of typical alerts and also other messages which you may get in the driver updating process, a number of which I've paraphrased and listed right here along with information on how to proceed:

QUESTION: So I have a Sony Vaio SVD13213CYB and the usb ports are not working. Optical 3 button mouses cannot connect nor can my USB both of which work on other computers. I have absolutely no idea what the problem is.

Although, I looked into device manager and found USB root hub xhcl had an exclamation mark next to it. It says that it cannot load the device driver for this hardware. The driver could possibly be corrupted or missing. (Code 39). Once I try to update the driver for it it says the driver is up to date. Does this have anything to do with it?

I've also tried uninstalling all the usb extensions and rebooting. It did nothing (All the extensions came back even xhcl with the exclamation mark).

I really have no idea what to do and any help will be appreciated.

ANSWER: Possibly the driver is corrupted or the USB devices are busted. Let's isolate the issue. Kindly follow these steps:

Power cycle - Remove the battery and all peripherals -> press and hold the power button for 5 seconds OR, if the battery is not removable, remove all peripherals -> look for a battery off button on the bottom of the laptop -> push the button for 5 seconds

How to Update Drivers with Device Manager?

Driver updates for Windows 10 and many devices (such as monitors, printers, and video cards) are automatically downloaded and installed through Windows Update.

While it's likely you already have the most recent driver, if you're having trouble with a device, you can try fixing it by updating the driver or reinstalling it. Here's how:

Select the Start button, type Device Manager, and select it from the list of results.

Expand one of the categories to find the name of your device, then right-click (or tap and hold) it, and select Update Driver Software.

Select Search automatically for updated driver software.

If Windows doesn't find a new driver, you can try looking for one on the device manufacturer's website and follow their instructions.

If these steps don't work, try reinstalling the driver: Open Device Manager, right-click (or tap and hold) the name of the device, and select Uninstall. Restart your PC and Windows will attempt to reinstall the driver.
